Lannoy, whose title is now Princess Stephanie, Hereditary Grand Duchess of Luxembourg, wore a family tiara consisting of 270 brilliant-cut diamonds set in platinum. @SydneyLux tweeted that Stephanie’s hair was done by Tom Marcineau of Maison CARITA-Paris. The flowers were a Maison Lachaume creation.

Inside the Cathedral of Our Lady of Luxembourg, there was a moment of silence for Stephanie’s late mother, Countess Alix de Lannoy.
